i have a 20g with 3 adult guppies, about a dozen month old fry and 7 cory catfish. just a few days ago i started to notice a brown "haze" on one of my plastic plants. And just over a few days it has gotten bigger. Not darker, still light enough to be easily overlooked, and there are even a few patches of it on the bottom and sides of the aquarium. (its so weird because it seems like you can see the leaf or something normally, but the edges are fuzzy brown)Should I just wash it off, or is this the beginning of a big problem?
PS- the water is fine, checked it when i first noticed, and today
